Letters Potent No. 105,079, dated July 5, 1870.

The Schedule referred to in these Lettere Patent and mlaking part of thesame To all persons to whom. these presents may come:`

Be it known that LFRANoIs M. HoLMEs, of Bos,- ton, in the county ofSuffolk end'Steteof Massachusetts, have invented e new and usefulImprovement in Folding Chairs; and do herebydeclare the sameto be fullydescribed in the following specification, reference being hed to theaccompanying drawing, ot ,which- Figure 1 is o. front elevation 'Figure2, a. side view; und

Figure 3, a. vertical section of u folding chair provided with myinvention. In carrying ont my present improvement the sent of' the.chair is to be hinged ton rung or bur firmly fastened to the upper arms'of the shorter pair of the curved levers, the said' he1',with the twoshorter levers :ind another hor or rung connecting them, composing a.rigid frame.

Then the seat is piroted to shorter levers, they are apt to become splitor broken bythe strain ou the.

points, induced by a, person while sitting upon the seat. It is lveryobjectionable, also, to hinge the sent to the tops of' the shorterlevers. f

In this chair thelegs and the side bars of the buck are formedby fourlevers, A AB B. lEach of the Vshorter levers B B crosses one of the buckor longer .levers- A A', the two at the crossing being pivoted togetheror connected by tfulcrum or joint-pin-Ta, going through one and into theother, orth'rou'gh both,

, if preferable.

The shorter levers are arranged outside of the longer' levers, and areconnected by two rungs or crossbars, b e.

The sent, shown et G,rests on and is hinged es represented at h',directly to the upper' rung or bor c such sent, whenihe chair isunfolded as exhibited in the drawing, also rests on` aroundVsul'iport-her or rung, e, whose lends are sustained hyprojec'tionsffextended from thelongcr levers, in manner us represented.

Furthermore, the two longer levers are connected, near their lower ends,hy means of e rung, g, and also at or nea-r their upper ends and middleshy two other rungs or hars, It t', fastened to projections k l k lextended` from suoli levers, the /who'le being :t1-ranged in manner asrepresented in the, drawing.

The two rungs, h t, compose part oi' the heck ijzunc, and muy beconnected by bers or lframe-pieces m m.

The seat is furnished with one or more hooks, n, to extend from itsreatr part, and hook upward around the middle rung e of the longerlevers.

From thezihove it will be seen that, when the sent is horizonte-l, itwill be supported Vby three rungs, und that. it has no direct pivotalYconnection with either of of the levers, it being hinged to thefrontonc ofthe said three rungs.

I claim- A foldiu, :,r-ch:iir, as mede with its sont C hinged to a.rung, c, rigidly fastened to the two shorter levers B B', :ind es havingtwo` other seat-supportingrungs, et, arranged and applied to the longerlevers, as described.
